Php 试图在现有的codeigniter应用程序中加载视图，需要关于我得到的错误的建议吗

我刚开始开发codeigniter应用程序

这个项目很简单，我只需要创建一个视图并从数据库中获取一些数据

然而，当我试图访问视图时，我总是会遇到这些错误

我不知道这些错误是什么意思

这是我用来在默认控制器类中加载视图的代码，它是该类中索引函数的一个单独函数

function watchlist(){
            $this->load->view("watchlist_view");
        }

以下是我在浏览器中访问视图的方式

localhost/watchlist/index.php/home/watchlist

这里是我得到的错误

    A PHP Error was encountered

Severity: Warning

构造函数主代码

class Home extends Controller
    {

        var $ministry_name = "Security";

        function Home()
        {
            parent::Controller();
        }

        function index()
        {
            Removed local redirect. All sites will now redirect to main site
            //Added a check to see if the user is still logged in.  If so, remain on the site.
            if (!$this->authorization->checklogin())
            {
                header('Location: http://mainsite.org/');
                exit;

            }
            else
            {
                redirect("/home/main");
                exit();
            }

        }

        function watchlist(){
            //Loads watchlist view
            $this->load->view("watchlist_view");
        }

看。在这里，您应该扩展CI_控制器而不是控制器，并且您可以使用通用构造函数和父构造函数：：u构造函数；而不是旧的同名样式。

好的，我要试试这个。谢谢
